Find and fix air leaks while improving performance through reliable blower door test in Raritan township, NJ. Our certified technicians support homeowners, builders, and contractors in finding hidden leaks, improving comfort, and ensuring compliance with NJ energy codes.

What Is A Blower Door Test?

A blower door test determines the air changes per hour of a house or building, ensuring proper ventilation as old air cycles out and fresh air flows in. Excessive air changes can cause problems since each exchange requires reheating or recooling, resulting in greater energy consumption and reduced efficiency. Excessive air circulation may cause drafts, discomfort from leaks, and indoor problems like condensation, mold, and moisture damage. A blower door test in Raritan township, NJ detects early-stage air leaks, enabling effective energy use and a more durable, comfortable living environment.

What Our Clients Say

How Is A Blower Door Test Conducted?

When performing blower door test in Raritan township, NJ, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. Technicians mount a calibrated fan onto the frame to achieve 50 Pascals of depressurization — similar to a constant 20 mph wind acting on the home.

As the fan removes air from inside, exterior air flows in through leaks and gaps in the building envelope. Using a sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal pressure. The collected data converts to air changes per hour (ACH), demonstrating how tightly sealed and efficient the home remains in NJ climates.

What Is A Passing Blower Door Test Score?

Homes built in Raritan township, NJ are expected to comply with the 2015 International Energy Conservation Code (IECC) or any newer local versions in effect. Typically, blower door test compliance means maintaining 3 air changes per hour or less for energy-efficient performance. Passing this requirement during a blower door test in Raritan township, NJ keeps your home efficient and aligned with local building code standards.

Why Do I Need A Blower Door Test?

Both NJ and local jurisdictions adopt the IECC energy code, making blower door test mandatory for new and renovated residential structures. Our experts assist home builders, contractors, and homeowners needing blower door test in Raritan township, NJ to ensure compliance with energy codes and complete final permits. A duct leakage test requirement applies if ducts or HVAC units are positioned outside the structure’s thermal envelope. Learn more about energy code compliance.

Homeowners experience real energy benefits from blower door test in Raritan township, NJ. The fan’s depressurization highlights air leaks, helping identify inefficiencies that can be sealed for savings. A blower door test may take just a few hours, yet its long-lasting impact can greatly improve your home’s comfort and energy use across NJ’ hot summers and cool winters.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Apply an appropriate air barrier, such as Tyvek or Zip Sheathing, making sure every seam is correctly taped for maximum performance.
Install insulation of the appropriate R-value and inspect to confirm it’s correctly fitted in all envelope areas.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Ensure all penetrations between conditioned and unconditioned areas—like attics, basements, and crawl spaces—are tightly sealed.
Local jurisdictions frequently publish compliance checklists — the Philadelphia version can be downloaded here.
With caulk, spray foam, and advanced thermal imaging, Local Energy Audits locates and seals leaks efficiently on-site./li>

Preparing for a Blower Door Test in Raritan township, NJ

Preparation for blower door test in Raritan township, NJ begins with switching off the HVAC system, as well as any bathroom and kitchen exhaust fans. We then perform a brief inspection throughout the home to make sure all exterior doors and windows are tightly shut — even those opening to garages, basements, or spaces outside the thermal envelope. After sealing the home, the blower door fan is installed in a central exterior doorway and used to lower pressure to 50 Pascals to measure airflow and leakage effectively. When the home reaches depressurization, outside air seeps in rapidly, helping identify leaks with greater accuracy. Through the use of a thermal imager, we find problem zones by detecting uneven temperatures in walls, ceilings, and surfaces connected to unconditioned spaces. Our technicians arrive with chalk, spray foam, and weatherstripping materials, ready to work with homeowners or contractors to fix visible air leakage problems right away. After sealing, we can immediately retest to confirm whether the desired blower door score has been reached, ensuring your home complies with local energy efficiency standards in Raritan township, NJ.

Blower Door Test for Contractors in Raritan township, NJ
